What is QA Testing and What Are its Benefits?
QA Technicians will tell you that QA testing is the most critical process in the software industry and, while this
is debatable, it highlights the significance of the practice. QA or quality assurance testing is crucial for any team
who is making software, applications, or even end-to-end full systems, and it is how these products are tested before they hit the market.
So, how exactly does QA testing work and what benefits can those who stay up to date with modern testing reap?
How it Works
QA testing is typically outsourced and, though there is a range of testing options, automated testing is the most common form of QA testing.
It involves the creation of specialized tests that automatically test a software product for flaws.
QA automated testing with good processors can test at an incredibly high rate, simulating user environments and making sure that there are minimal errors.
Manual QA testing still has its place in many instances, but automated testing is now often the most appropriate test of the software.
There are many standard software tests, and the following are often automated:
- Smoke tests – checking no showstopper defect prevents detailed testing
- Regression testing – testing a product as a whole
- Sanity tests – tests that determine if a new software version is stable enough for further tests
Proper QA may also involve different consultation services, including when performing the following:
- API services testing
- Desktop application testing
- Mobile app testing
- Website testing (including a web app and mobile sites)
- IoT device testing
Open source or Professional?
There are many different open source testing tools available, including Selenium WebDriver, Appium, SpecFlow, JMeter
and even Instruments utility in Xcode, so many people question whether they should go to a professional for QA testing.
Open source tools are high, and they are often used by professionals, but if you are not an experienced tester, this question
is akin to asking if you need a plumber because you have free piping. Unless you have the expertise, testing either will not work
or be a prolonged process as you teach yourself.
Benefits of Modern Automation QA Testing
Modern automation QA testing beats manual QA testing in many instances for the following reasons:
- It saves time – this is obvious, but the time saved by not needing to write extensive testing scripts can be significant.
What is more, any test scripts that are written using the automation tools can be reused, saving time in the future.
- Tests can be run 24/7, ensuring thorough checking and efficient use of time with no fatigue.
- They allow you to test during development, which previously might have taken too much time.
Testing during development allows bugs to be dealt with as the product is built, creating shorter product development cycles.
- Tests can be carried out in different environments – e.g. with web testing, you do not need to run manual tests in each individual browser
- A (much) smaller testing team, leading to cost savings for developers.
